DRIVING MECHANISM FOR CARDING-MAGI-IINE STRIPPER ROLLS.

Application filed March 10, 1926. Serial No. 93,737.

It has been proposed heretofore to apply a continuously operatingstripper roll to the cylinder of a carding machine, and such aconstruction is shown in British Patent No. 216,480. The presentinvention relates to driving'mechanisms for such rolls and it aims tofacilitate the installation of such rolls in carding machines. It is thechief object of the invention to devise a driving mechanism for such aroll which can be manufactured economically and can be installed withaminimum of labor.

The nature of the invention will be readily understoodv from thefollowing description when read in connection with the accompanyingdrawings, and the novel features will be particularly pointed out in theappended claims. In the drawings, I Figure 1 is a side view of a portionof a carding machine equipped with a mechanism embodying this invention;and

Fig. 2 is a plan view of apart of the machine shown in Fig. 1.

In the drawings the main cylinder of the machine is indicated at2, theleader or licker-in at 3, and certain of the flats at 4. 1

The cylinder 2 is mounted. on the main shaft 5 of the machine and thisshaft is pro- 'vided with fast and loose pulleys 6, and 7,

respectively. The fast pulley 6, in addition to having a face to receivethe main driving belt, is provided with a peripheralflange 8 which isgrooved to form an auxiliary pulley adapted to receive a round belt.Normally this auxiliary pulley 8 is not used, but it is provided for thepurpose of affording a convenient means for driving the grinding rollwhich is used in surfacing the card clothing on the main cylinder 2. Thecon struction so far described is substantially like that of a commoncommercial type of carding machine.

The stripper roll is indicated at 10, and it is supported on a shaft 12which is mounted above and slightly to the left of the lickerin, asshown in Fig. 1. This roll is supported in two bearing brackets whichare bolted to the machine frame, one of these brackets being shown at13, Fig. 1.

The driving mechanism provided by this invention comprises a small gearor pinion 14 secured fast on the stripper roll shaft 12. Another gear 15meshes with and drives the gear or pinion 14:. Both of these gears arecompletely enclosed in a casing which comprises a main casing section16and a removable cover 17 which is bolted or screwed to the mainsection 16. The gear 15 above mentioned is mounted on a shaft 18 whichrotatably supported in the casing 16 and cover 17 and projects throughthe cover. A pulley 19 is mounted fast on this shaft outside the casingand is arranged to be operatively connected to the grooved pul ley 8 bymeans of a driving belt 20.

The stripper roll shaft 12 fits snugly in a hole formed through the mainsection 16 of the casing so that this entire casing may pivot 011 theshaft 12. Projecting from the upper side of the casing 16 is aplate-like extension 21 in which a slot 22 is formed, this slot beingcurved about the axis of the shaft 12 as a center. A bolt 23 projectsthrough this slot and is threaded into the frame of the machine. It willthus be observed that the casing is supported partly by the shaft 12 andpartly by the bolt The pivotal movement of the casing permits theadjustment of the tension of the belt 20 and the bolt 23 serves tosecure the easing in various'positions of adjustment.

Under some circumstances it may be desirable to make this belttightening operation automatic, and for this purpose a spring 24 may bepositioned in the slot 22, bearing at one e'ndagainst the-bolt 23 and atits op- 'posite end against the end of the slot, the

pressure of this spring tending to tighten the belt 20, as will beobvious from an inspection of Fig. 1.

Usually in installing the device, one of the bolts which holdsthebracket 25 in place is removed, and this bolt, or one like it but havinga larger head, is inserted through the slot 22 and threaded into thehole from which it was removed, so that it is unnecessary to drill andtap a new hole in the frame of the machine. I

It will now be evident that this invention provides a very simplemechanism for driving the stripper roll 10. This entire driving unit canbe manufactured very economically, and it can then be installed on themachine with very little labor. The fact that it utilizes the grooveddriving pulley 8 with which the machine is already equipped is animportant practical advantage since it avoids the necessity of providingand installing a separate pulley, which operation very likely wouldrequire the removal of the fast and loose pulleys 6 and 7 from the mainshaft. The casing may be packed with grease to lubricate the gears andbearings, it completely protects the gears from fly, lint and dirt, andit also forms an effective guard to prevent the clothing of theattendants from being caught in the gears.

While l have herein shown and described the best embodiment of myinvention that l have so far devised, it will be evident that theinvention is not limited to embodiment in the precise form shown.

Having thus described my invention, what i desire to claim as new is:

1. In a carding machine, the combination of a stripper roll, a shaft forsaid roll, a gear on said shaft, a second gear meshing with the firstgear, a pulley rotating with said second gear to receive a driving belt,and a support for said second gear mounted for pivotal adjustment aboutthe axis of said shaft to adjust the tension of said belt.

2. in a carding machine, the combination of a stripper roll, a shaft forsaid roll, a gear on said shaft, a second gear meshing with the firstgear, a pulley rotatable with said sec nd gear and adapted to receive abelt driven from the main shaft of the carding machine, a casing forsaid gears mounted for adjustment about the axis of said shaft, andmeans for holding said casing in differ ent positions of adjustment.

3. In a carding machine, the combination of a stripper roll, a shaft forsaid roll, a gear on said shaft, a second gear meshing with the firstgear, a casing enclosing said gears and mounted for pivotal adjustmentabout the axis of said shaft, a second shaft supporting said second gearand mounted in said casing, a pulley mounted on said second shaft andadapted to be belt driven, and a spring tending to move said casing in adi rection to tighten said belt.

4. 1n a carding machine, the combination of a stripper roll, a shaft forsaid roll, a pinion on said shaft, a gear meshing with said pinion, acasing enclosing said gear and pinion,a second shaft rotatably mountedin said casing and supporting said gear, a pulley mounted on said secondshaft and adapted to be belt driven from a pulley on the main drivingshaft of the machine, said casing being mounted for pivotal adjustmentabout the axis of said stripper roll shaft to adjust the tension of saidbelt, said casing having an extension projecting therefrom, and meanscooperating with said extension to hold the casing in differentpositions of adjustment.

A driving mechanism for the stripper roll of a carding machine,comprising a gear for driving said roll, a second gear meshing with thefirst gear, a casing for said driving gears, and driving means for saidsecond gear, said casing having a part adapted to be secured to saidmachine.

A driving mechanism for the stripper roll of a carding machine,comprising a gear for driving said roll, a second gear meshing w the.;rst gear, a casing for said gears, a pn ley rotatable with said secondgear, and a projection extending from said casing and adapted to besecured to a part of the card in g machine.

7. A driving mechanism for the stripper roll of a carding machine,comprising a pinion for driving said roll, a gear meshing with saidpinion, a casing enclosing said gear and pinion, a shaft mounted in saidcasing and supporting said gear, a pulley fast on said shaft, and aprojection extending from said casing and adapted to be adjnstablysecured to the carding machine.
